TYPEWRITING MACHINE.

Application filed March 10, 1922. Serial No. 542,663.

T0 (ZZZ whom it may concern:

Be it known that I, F Rnmnuo W. HILLARD, a citizen of the United States of America, and a resident of Tottenville, in the county of Richmond and State of New York, have invented certain new and useful Improvemy prior Patent No. 1,296,957, patented March 11, 1919' and reissued October 18, 19521, Reissue Number 15,209, although the present invention may also be applied to other machines.

In'the drawings herein I show an improved means. for holding the carriage against endwise movement when free of the escapement; and also a latch lock for holding the carriage in its lifted position, and a key and means actuated thereby for unlocking the latch lock so that the carriage may bc lowered from its lifted position back-to its normal writing one.

My invention also contemplates various other detail improvements in" connection with the before mentioned objects, which imirovements will be more fully pointed out in the accompanying drawings, specification and in the appended claims.

in the accompanying drawings -wh1ch form a part of the specification, the im prm'ements are fullyillustrated. The machine is generally of the type; of the machine of my said prior patent, Reissue No. 15,209, excepting for the various modifications and improvements herein shown and described, and it will therefore be understood. that l have left out from the various drawings those parts of the machine which are unnecessary to illustrate the invention, thereby making the illustration of the various features of the invention simpler and clearer than they would he were unnecessary parts shown.

Figure 1 is a plan view of the machine with many parts omitted.

Fig. 2 is aside elevation of the carriage parts shown in Fig. 1. This view also shows in dottedlines the position of the carriage when in elevated position and locked in such position. Fig. 3 is an enlarged detail of the latch lock for holding the carriage, preferably positively in its lifted position, and part of" the means for releasing the lock to permit the carriage to be lowered.

Figs. 4:, 5, 6,7-and 8 are detail views of the ball bearing race ways and its truck, together with the latch lock for holding up the lifted carriage, and the truck lock for preventing endwise movement of the lifted carriage. c

' In the drawings, referring particularly to Figs. 1 and 2, the preferred embodiment of my invention comprises a truck 1. Extending forwardly and upwardly from this truck are the brackets 2 which pivotally support the shaft 3, which latter forms a pivotal support for both the inner and outer carriages. The outer carriage, which I will also term the non-shiftable carriage is shown at and this carriage carries rearwardly extending lugs 5 which pivota-lly engage eccentric bushings 3 on shaft 3. The inner carriage, also termed the shifting carriageis shown at 6 and this carriage is provided with suitable brackets which support studs 7 which pivotally engage the forward ends of the shift arms 7. The hearings in the forward ends of these shiftiarms l are closed with caps 8, since it is necessary that'the carriage be retained -lI1fPOGlli'l0I1 when swung upwardly. The opposite (rear) ends of the shift arms '7 are dixed to the ends of the shaft 3, as shown in Fig. 2, being pinned thereon. 1

The inner shi fting carriage is adapted to be vertically raised and lowered "by any of the well'kn'own shift constructions, for exampleas-shown in Fig. 2, in which 9 represents part of the linkage connecting -with the shi ft key. As this mechanism is the well known mechanism of the Underwood typea'i ri'ter 'as shown in msaid rior j atent further description and illustration be-- lieved to heunnecessary. Thefront end of the -'ou"terno1i-s"hifting carriage 4, is provid'ed with the "usual supporting Wheel 10 enclosed in casing ll and runningon front guide rod 13, and there is the =usuallocking linger 12 extending forwardly on the carriage beneath the upper front locking bar 2, to loelc down the f'ront o'f ehe carriage at was proper 'glevl while permitting it to run freely in its line of travel on" the front guide sat-1 This is the usualconstruction so that further desori- 'a'tion is' believedunnecessary. 'Thehinge jointyat th'e pivot shaft 3 hetwe'cn the carriage and "the truck, permits "the carriage to a'c'l iust itself to 'its position on the guide rail 13and thus prevents fric- -tion by'undue pressure on the rail or looking bar 1 2, My truck, in addition to its ball bearing anti friction raee' ways advantages,

iafl'ortls a staple anchorage for the carriage =when in its lifted position.

' The truck 1 is mounted upon the 'machine in the following manner, Two upwardly iprojecting brackets "14 are mounted on the rear of the *m'aehine frame. llhe' upper and lowor race ways 15 and 16 *aresecurcd to t'hese arms and are preferably adjustable toward and from each other. These race 'ways are fully described in my said ,prior Patent Reissue No. 15,209, so :that i further description, excepting a brief statement iof the parts employed, is fbelieved iunnecessary. .iL-is shown, :the upper rail is adjustable itowar'd :theilower one 'by adjusting screws 1/? LiIn the race ways 1 :utilize'bearing balls L8 two Lin' eachfhearing as shown, although rm'ore iballs may be employed at' will.) and the intermediate anti-friction balls (one between each two bearing balls) 19. The halls and their anti-creeping cage 20 move at onehalf the speed of the truck and carriage. Upon the front of the truck and adapted to move in unison therewith is a downwardly facing rack 21 which engages a pinion 22 carried-by the ball retaining cage 20. Upon the lowerrace way I mount a second rack 23 which also meshes with the pinion 22.

'As previously explained the truck 1 has upwardly extending brackets 2 which pivotally support the shaft 3, and the shifting arms 7 are pinned to the ends of this shaft and the usual springQAl 'is coiled-about the shaft-to assist in li'fting'the inner carriage 6 in its case shifting movements. I also employ a secondspring 25to assist in lifting the shift rail and inner carriage to upper case position, similar to the-corresponding sprin'g'of my said prior patent. Upon the rear side of thetruck there is mounted the tabulatortruclrplate 26, which serves as a part of the tabulator mechanism; and screwed upon the plate 26 is the margin stop plate 2 6,a ll as in my saidprior patent. "The tahu la'tor .key 27, key lever 28 and pull bar 29 are the same as in 'my said prior patent and therefore need not be described indetail. The pull bar is operated bythe hey"through'the depression of the key lever 28, and'thus rocks the rocker armBO, which "iirturn rocks the-t-abulatorpivot bar 31 and *thus-swin'gs the tabulator rocker frame 32 and tahula-tor stops 33 forwardly to operate the tabula'tor. These parts are similar to I doperate 'in' the=same way as in my said p. L ent, and since 'my tabulator in- 'YEHLlOH -1s fully described therein further tleser' been here described because such -tabulator operating unchanism constitutes a part of my I arriage releasing 1ncans,'the latch lock member 84 being mounted thereon and the swinging-of the tdbulator rocker frame beutilized to disengage tooth 36 of said meniber 34 from tooth 52 'of the carriage member 41 of the latch look as illustrated in l ig. 8.

At the left hand end of the tabulator =rooker frame 32 (looking from the rear of the machine asseenin Fig. I mountone 'in'ember 8d -of the"carriage latch look (see also l ig. This member is fastened to the leftend of the tabulator rocker frame 32*bytwo screws and at its upper end is providechwith the rearwardly facing latch lock or *loolring t'ooth-36, which constitutes one of the two engaging members of the latch lock; The other engaging member of thelatch loc'k is mounted on the carriage and will now be described. Referring to 'ill'irgs. land 2, i 7 is a back rod which forms a support for hepaper margin guide'in the machine of my former patent. T This rodis --t-ion=is deemed unnecessary. It has carried on brackets 38 which are rigidly mounted on the side plates of the inner carriage frame 6, beneath the cover plates 39 and are bent inwardly toward each other crosswise of the cover plates, in the usual way and as appears in my said patent and in ti gs. 1 and 9 herein. They are then bent upwardly and rearwardly and take in the rod 37 which is squared and screwed (in a set position determined by the squaring and the position of brackets 38) to the brackets by the screws 40, or by-a single screw 40 at the right hand end of the rod as seen looking from'the front of the machine in Fig. 1, with the left end of the rod merely journalled in its bracket. Itv will be observed that by bending the inwardly extending portions of the brackets 38 forwardly or rearwardly relatively to the carriage, the rod 3'? may be moved forwardly or rearwardly relatively to the carriage and also upwardly or downwardly relatively to the riage by bending the brackets for that pose. I employ these means as an adstment for the carriage member 41 of the latch lock relatively to the tabulator member, to bring the two members into proper re ation so that their teeth 36 and 52 will engage properly with each other in the lifted, locked position of the carriage shown in dotted lines in Fig. 2.

The locking member ll is slidably mounted on the rod 37, and when adjusted to the proper position thereon is clamped to the rod by one or iore screws 42 (two screws being shown in Fig. 1) which take into the usual slot 43 on the rod. The rod is milled on parallel sides at the right end (looking from the front of the machine) and is passed through a corresponding perforation with parallel sides as usual, in the right hand bracket 38. This serves to properly locate the slot 43. By bending the upper end of the bracket with the squared perforation angularly the position of the slot will be varied and I employ this means as stated, to adjust tooth 52 to tooth 36 of the latch lock.

The means and method of locking up the lifted carriage by a frictional lock were fully described in my said prior patent and the carriage is also normally locked down in ope 'ative writing position by the well ltnown mechanism shown and described in said patent and shown herein as locking bar 12 and this bar is provided with the releasing slot il. hen the carriage is positioned at a point to the right of the beginning of the line of print, as described in my said prior patent, the locking linger 12 will be in the releasing slot a l and the carriage may be lifted. As soon as the carriage begins to be lifted, the rack 46 will be lifted up off from the escapement pinion connected with the escapement wheel 48 and the carriage will be freed from the escapeinent and,

under the influence of the usual main spring propelling means, tend to advance. But locks 44:56 and 4950 are provided to re sist and overcome this tendency. I will describe these locks more fully hereinafter.

As the carriage is beinglifted and approaches its fully raised position, the rod 37 engages with the upper beveled cam face 51 on the right hand bracket 14 (i. e. the one shown in Fi 2). It will be understood thatthe inner carriage, during the initial lifting movement, is in lower case position, being maintained therein by the influence of gravity. But when the rod 37 engages cam face 51, on a further lifting movement of the carriage and resultantfurther rearward movement of the rod 87, the rod being forced against cam face 51 lifts the inner carriage faster than the outer carriage is being lifted and hence shifts the inner carriage into upper case position in the outer carriage, as in my said prior patent. Then on the further and final rearward movement, while the teeth 36 and 52 are snapping together to lock the latch lock, the rod 37 passes into notch 51 and the inner carriage is thus maintained in its upper case position, so that both carriages are locked together wlnle the latch lock remains locked, with the here ficial results described in mysaid patent,- of thus locking the inner carriage rigidly in the outer one. While certain features are therefore similar to my said patent, my pres ent device differs from the said former one in particular which I will now describe.

In my prior patent the notch, corresponding to notch 51 herein, was depended on to hold the carriage frictionally locked in its raised position, a ainst the influence of gravity and other influences to cause it to fall. In my present device I do not depend on a gravity resisting friction look but instead provide a bolted or hooked lock or a latch lock, or a lock having two engaging inen'ibers, one of V which can be manually withdrawn from the other to unlock the lock. This results that I can employ a key and means operated thereby to withdraw the bolt from the lock or to unlock the latch lock, instead of being forced, as in the prior patent, to exert a strong pull on the carriage to forcibly pull the rod Ell-outof the, notch 51". In my prior patent ,are had to bee ercised not to make the friction look too strong as other wise it was difficult to pull the carri age down from locked position; and on the other hand, if the lock were not made strong its reliability against gravity was less and the carriage was apt to accidentally fall.

In the present device the notch may or not as preferred, be made strongv enough to act, in connection with the bolted lock or latch look, as an auxiliary frictional look, so that the carriage will not fall accidentally, even it the operator depress the release key to unil l Iil

which t as my preferred form, :the "latch lock above referred to. The operation of this lock iszas follows. In the rearward swinging movement of rod 37 :as the carriage 1s being lrfted, the 'rod first engages cam face 51 and liftsthe inner carriageint-oupper case EPOSltion, as above 'described. This compound movement of the inner carriage, relatively to the outer carriage,serves to bringthmperip'hery of lock 41 below tooth 52, in line with and above the upper inclined surface of locking unember 34 above :tooth 36,--sozthat on a further rearward amovement (if bar =37 the docking member 34 iIIlClYtflbLllEttOl bar 32 will be cammed forwardzas above described, allowing the tooth "52 toswing down below tooth 36 tolieengaged thereby'as soon as the 'tab-ulator rocker frame 32 swings back to normal position under the influence :of its :usual returning spring 53, of any prior vpatent and the well known Underwood struc' ture, thus engaging the latch lock members together, as shown in dotted *line position Fig. 2.

I will now describe 'the zunlocking means for the Tlatch lock. Since the iorward and then backward movement :of the tabulator rocker frame, :as above descnibedyserves ito lock the letch -lock, it is ObV-lOUS that :a repeated forward swinging movement of the tabulator rocker frame will also st-rve to unlock :the latch look, :by evithdrawing the tooth 86 out o f'tooth 52 as shown in Fig.

The means swinging the rocker frame forward to unlock the latch lock are the l'abulator keyil? .und"the'conneetions therefrom to the rocker frame.

These include the key lever 28, pull bar 29 audthe rocker arm 30 "fastened to the -'rocl '"r frame. The pin (S -Hand slot (55)between the :key lever wand the pullbar 2S) peiunit'the tabulator frame to be swung forward during the locking increment -u-'ithout depression of the key 27.

But in all cases in my present device the ease of the carriage docking 'is xr-etained in strong contrast to the 'hard action withmy former friction-loch.

The No. 1 loek controlled the -znitial lift, the No. 2, the intermediate one "andthe No.8 the final lifting period. Hence the carriage was continually under locking control durlng the whole lifting movement.

But thethree locks were required and even these had 'to be in veryaccurate adji' tment or the carriage was apt to escape through between the locks for an erroneous endu'ise "feed and that was very'bad. il his d 'I'ha'vo'now overcome and in fact,-can safely dispense with the intermediate or No. 2

locket the prior patent, thus greatly simplifying the locking mechanism, particularly when applying the improvement to 'machines already 1n use.

In "order to make the improvement clear *1 will explain the mechanism ot'the former zpatent which resulted in. 'the no d of three very earei'ully adjusted locks. "fho reason of the dificulty of the device ol' the said '2 prior (patent w as that in that :pateut the ca:- riage unember of the No. 3 loch :a'asmounted on the shaft whichrloiuns the-pivotal support ior the shifnngcarriage, i. e. the shaftinum- ?bered 3 herein. Therefore saidniemher vibrated transversely toward and away from the other member of the lock when the inner marriage was shifted'to upper case 'and lower case ipositions in'the outer carriage. Hence the carriage member had to be set normally a considerable distance -forward ofthe other memh r so as not to interfere therewith in the uppercase position of theinner'carriage. This resultedthatthe filo. 1 leck'became un i culty did not always become reliabl' enga ed.

t c; to

prior to release of the No. 2.

In my present device No. 1 look is the same as No. 1 look of the prior patent; lilo. 2 lock may be dispensed with and the race way member of No.3 lock is the same in the patent as herein. But the carriage inem ber of the No. 3 lock is different and differently located herein from the one of the prior patent. In my present device the carriage member of lock corresponding to look No. 3 of the patent is mounted securely on the non-shifting carriage 4, being screwed to the frame thereof, and is numbered 49. The part 49 is therefore non-shifting in the upper and lower case shifting movemjnts of the inner carriage. It has no movement toward or away from the race way member, excepting during the lifting movement of the carriage structure in raising'it to lifted nonoperative position. Hence the member 49 may be normally set close up to the race way member 50 in the operative position ofthe carriage and the parts 49 and 50 become reliably engaged before the carriage has been lifted far enough to disengage tne contacts 56 and 57 of the No-l lock. Of course the No. 2 look of the prior patent may still be employed with my present improved device but it is not necessary.

Fig. 9 differs from Fig. 1 in that it shows a wider carriage machine. The mechanism of the Underwood wide carriage machines differ somewhat from the standard width ones but the mechanisms are so well known that no particular detail description is be carriage at an intermediate point in its line of t Mel and in that case a d flerent type of restraining lock is preferable. Fig. 9 shows such lock.

Since the carriage shown in Fig, 9 has two support wheels at the front of the machine,

numbered 10 herein, 1 provide two slots 44 for the escape of such rollers 10, in the upper front locking bar 12", corresponding to the predetermined intermediate point at which the carriage is to be lifted, and I mount midway at the rear of the carriage, on the frame of the non-shifting carriage 4, the locking finger 49, by rigidly screwing it on the carriage. Upon the upper race way the tooth 52.

rail 15 I rigidly fasten the double restraining arms and 50 The front lock comprises the rollers 10 and the slots 44 with their right and left hand banking edges 57 and 57; and the rear lock comprises the locking finger 49, with its banking edges 4.91and 49, and the restraining arm 5O with its banking edge 59 and the restraining arm 50 with its banking edge 50..

The reason for the right and left. hand banking stops in Fig. 9 is that the carriage is lifted in an intern'iediate position. Hence a margin stop can not be conveniently employed and its functions are performed by the right hand banking stops of the lock of Fig. 9.

In the operation of my device, in Fig. 1, I draw thecarriage to the right to the limit of its travel, depressing the margin release key 58 inorder to pass the margin stop 59. This will bring the carriage pointer 60 slightly to the right of the zero point on the scale, or the graduation where the first letter of writing can begin, the carriage being thus beyond and outside of its normal writing position. WVhen the carriage has been.

thus moved to its limit to the right with the carriage pointer to theriglit of the first graduation on scale 61, the margin stop 26 at the rear of the carriage will bank on the bracket 14,as shown in Fig. 6. The shoe 12 will also be in the slot 44, so that the carriage will be unlocked and free to be lifted. Then I lift the carriage upwardly and back until the rod 37 engages cam 51 and cams the inner carriage into upper case position in the outer carriage. This brings lock 41 into position to engage the-cam face on top of locking member 34 and cams the tab-ulator rocker frame and locking member 84 thereon forwardly so that the tooth 36 escapes over Then the spring 53 restores the tabulatorrocker frame rearwardly to normal position and the tooth 36 engages in tooth 52 and the carriage is locked up, as above described. lower the carriage I preferably take hold of the carriage to hold it from falling too rapidly when unlocked. Then, with the other hand, I depress release key 27, thus witln drawing tooth 86 forward out of tooth 52 and then lower the carriage to its normal or writmg posit-ion.

In Fig. 9 to lift the carriage, I simply,

move it into the position wherein the rollers 10 are directlyin the slots 44, as shownin Fig. 9, and then lift upwardly, the rollers 10 passing up through the slots 44 and the locking finger 49 swinging down between the double retaining arms 50 and 50 The latch lock is the same in the structure of Fig. 9 as in that of Fig.1 and therefore the carriage of Fig. 9 looks up and is released in the way already described.
